DAiviPER-GAGE.

To (all whom #may concern Be it known that I, HERMAN GOLDBERG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful .improvements in Damper-Gages, 'of which the following is a specification.

My invention relates to gages for draft mechanism and has for one of its objects the provision of a simple and efficient gage means so that Aan operator may quickly and easily set theVY damper arrangement of a furnace, and the like, tooperate in any desired manner.

A further object is the provision of a gage plate for damper mechanism having a plurality of buttons' or other damper chainengaging vmembers which are adjustably mounted in the plate.

A still further object is the provision of a simple and eilicient gage plate forvdamper mechanism which can be easily and conveniently secured in convenient position to an operator.

Other objects will appearhereinafter.

' An embodiment of my invention is indicated in the accompanying drawing, forming a p art of this application, and in which-` Y Figure 1 is a front view of a furnace equipped with a device embodying my invention; and

Fig. 2 is an enlarged fragmental section taken on line 2-2 in Fig. 1 of my improved gage.

In the drawing l have indicated a furnace arrangement 5 equipped with a smoke pipe having an enlargement 6 housing a damper with a lever 7 disposed on the outside of said enlargement. My improvement it will be apparent is capable of use with various forms of furnace and draft control mechanism, that shown being simply illustrative.

A check draft damper S is hinged at 9 to suitable parts of the smoke pipe. A iiexible member 10, which in the present instance is indicated as being a chain, is connected at its lower end to lever 7 andextends upwardly and over a pulley 11. A flexible member or chain is attached to the check draft damper 8 and extends upwardly over a pulley 14 and then horizontally for a distance and attached to a wireor its equivalent and the latter attached to a chain or other flexible member 153 at a point 12. The chain 13 ex- .specificationmeters-Patent Patented Aug. 1o, 192e. Application le. November 24, 1919. Serial No. 340,144.

tends through a pulley 14 and downwardly to a ring 17 for attachment to my improved damper gage. The upper end of chain 10 is attached to the chain secured to damper 8 in any desired manner and may be attached where the last-mentioned chain is secured to the wire above refer ed to. rllhe length and arrangement of the flexible members, chains or wires, may be varied to suit different requirements.

My improved gage comprises a plate or Vblock 18 which is adapted to be secured to a portion of the furnace, as indicated in Fig. l, or to any other convenient object so as to be easily accessible to the operator. It is very convenientto have the plate attached to the furnace as indicated so that the operator during fixing the lire can set his draft mechanism quickly and easily.

In the form of my invention illustrated I have shownl a plurality of slots 19 extending longitudinally of the block or plate 18, and in each Vslot is disposed the stem 2O of a button or other member 21. I preferably arrange the slots 19v so-that they are of various lengths and they may be graduated as indicated in Fig. 1. At the top of the shortest slot may be arranged the notation Bankf Above the next longer slot the notation Mild. Above the next slot the notation Cold and above the next or Vlongest, slot the notation Ex cold. 1

have indicated these notations simply as suggestive. It will be apparent that other nowhen rin r 17 is in engagement with the dif- C C3 b ferent buttons 21 the damper will be arranged so as to control the iire for the weather indica-ted by the notations on the plate 1S. Nuts 23 are threaded on the stems 2O and engage shoulders 24 of recesses 25 on the back of the plate adjacent the slots. The shoulders prevent the nuts from turning in tightening and loosening the buttons 21.

`*Weather demands.

Other locking means may be provided if desirable.

Inusing improved gage the gage set in a convenient position, suchV as on the furnace as indicatedy in Fig. l5 and the per-f.l son installing the same arranges the chains' Vto control the damper` mechanism as indicated. above. 'Upon the reman or person Who takes care of the furnace desiring to start a re he places the ring 17 on button 22 and permits it to remain there until his fire is started. Then if .the Weather is mild he pulls the chain down engaging ring 17 Withthe button 21 of slot marked Mild. If it happens that the Weather is colder he eitherplaces the ring 17 on the button under the notation Cold .or EX. cold, as thel Weather demands. AWhen it is desired *toV bank the fire for the night or at other times when Very little or no fire is requiredlthe operator pulls the chain down and engages the ring 17 onthe lowermost button 21- in the slot under .the notation Bank. Vhen the lire is banked and the V.operator desiresl to start up the iire he simply takes the ring off of thebutton under the Word v Bank andplaces it on button'22until lhis fire has livened up suficiently, then moves the ringy 17 to one of the buttons under thc notations Mild, Cold or EX. cold, as the the fire.' The only thing he need do is toy select the button under the proper notation and engage ring 17 with this button to control his fire.

I claim 1. The combinationwith a furnace draft *sitjion of adjustment.

Y It will be apparentV therefore that no adjustment or guess WorkV by the operator is necessary for controlling engaging button adjustably mounted in each slot. V

4. In a furnace draft control means, a controlling gage comprising a plate having a plurality of -longitudinal slots with recesses along the slots providing a shoulder at each side of. each slot; a draft chain-engaging button at each slot on the-front of the gage; anda initV in each recess With its sides substantially engaging said shoulders and threaded on one 4of saidbuttons locking the Vlatter on said gage..

5. In a furnace `draft control means a controlling gage comprising a plate having a plurality of longitudinalv 'slots graduated in length; and a plurality of draft chain buttons adjustably disposed in said slotsat different Vrecesses from the lower end of the plate, the'button lin the shortest slot being nearest the lower end of the plate.

In testimony whereof Ihave signed' my name to this speciiication on this 20th day of November7 AvD. 1919. f
